Abstract
"SENSOR PARA DETECTAR DESCARGAS PARCIAIS EM UMA CUBA DE APARELHAGEM ELéTRICA". O sensor (15) de descargas parciais dentro de uma cuba (1) de aparelhagem elétrica cheia com um fluido dielétrico, compreende uma antena (16, 18) sensível às ondas eletromagnéticas geradas por essas descargas parciais. Nesse sensor a antena é formada por dois eletrodos separados por um ressonador dielétrico (17). Com essa disposição, o sensor apresenta uma sensibilidade melhorada nas ultra-altas freqüências, ao mesmo tempo em que tem dimensões nitidamente inferiores às dimensões de uma antena clássica destinada às ultra-altas freqüências.
